Subject: [ruby-core:58205] [ruby-trunk - Bug #9013] Crash on start


Issue #9013 has been updated by zapped (Alexey Shumkin).


I confirm this bug.
I had ruby 1.9.3p194 installed. Today I've tried to upgrade. I've downloaded ruby 1.9.3p448 (7-zipped version). After unpacking running "ruby -v" gives 
 ruby 1.9.3p448 (2013-06-27) [i386-mingw32]
but
 ruby -e 'p nil'
gives nothing.

I suspect this is connected with RubyInstaller as far as previuos version 1.9.3p194 has msvcrt-ruby191.dll of different size. When I put it to ruby's v1.9.3p448 folder
 ruby -e 'p nil'
gives expected
 nil
but gem install bundler (for example) failes with the error (nearly translated from Russian) "Cannot find entry point to ruby_enc_find_extname in DLL msvcrt-ruby191.dll"

After reverting back that DLL. I've got "internal:enc/prelude>:3: [BUG] Segmentation fault" error once.

I used RubyInstaller to install Ruby on Windows 7 (32-bit). I have many gems installed, though I'm not able to run gem list (no output). In my scripts I use mechanize.

I get the following error when I start irb:

C:\>irb

I can run ruby as a service using System account (Redmine works fine on Thin). But when I try to run it from my account I get the following:

C:\www\redmine>ruby script/rails -e production -p 3000

Re-installation fixes the problem for a while. And I can't figure out what's causing the bug to reappear.
